Kinetic Energy (KE)

Back

Energy of motion.

Front

Potential Energy (PE)

Back

Stored energy that can be used later.

Front

System

Back

A group of parts organized to work together.

Front

Law of Conservation of Energy

Back

Energy can change forms (transform), but cannot be created nor destroyed. This means that energy is not lost or gained from the system during a transformation.

Front

Energy Transformation

Back

Changing energy from one form to another in order to do work. Example: Gasoline (Chemical Energy) → Car moves (Mechanical Energy).

Front

Joule (J)

Back

The SI unit for energy.

Front

Generator

Back

A device that converts mechanical energy (KE) into electricity.
